With this AudioVisualizer you can see and hear scales, intervals,
modes, and/or the notes you play on an on-screen keyboard.
For scales and modes, look for the different interval patterns (whole steps, half steps, etc.)
that make up each one. Notice how these interval patterns remain consistent when you transpose
the scale or mode to a different root note.
For intervals, notice how easy it is to identify them and to differentiate between them.
